Let's get this math done. We have 548 and we're going to multiply it by 12. This is the same as taking 548 and adding it to itself 12 times.
Step 1: 0 + 548 = 548
Step 2: 548 + 548 = 1096
Step 3: 1096 + 548 = 1644
Step 4: 1644 + 548 = 2192
Step 5: 2192 + 548 = 2740
Step 6: 2740 + 548 = 3288
Step 7: 3288 + 548 = 3836
Step 8: 3836 + 548 = 4384
Step 9: 4384 + 548 = 4932
Step 10: 4932 + 548 = 5480
Step 11: 5480 + 548 = 6028
Step 12: 6028 + 548 = 6576

So, 548*12 = 6576
